Commercial Paint Mixer Solutions

Industrial mixers chosen for commercial paint production are critically important.  New formulations are continually evolving in many ways.  Whether its new colors, longer-lasting sheen or perhaps increased protective properties these products require more complex production processes and specific equipment to guarantee each batch is produced repeatably and with full homogeneity.  Utilization of the right mixer during pigment addition, let down processing and, finally, suspension of settled solids can make the difference between poor product performance and success for the end… Read More

How to Operate a Variable Speed Electric Disperser

The disperser comes with a hand wheel control for varying speed, a pneumatic air cylinder lift, safety shroud and up to a 55 gallon container holder. Use the pneumatic lift system to raise the air cylinder, then lock the drum into the container holder, fill it with the material, and finally lower the air cylinder into the drum and start.   Which Disperser Do I Need? Consider our small ½ to 3 horsepower HS-105, HS-115, HS-315, HS-320 or HS-300 electric… Read More

Fundamentals of Dispersion – A Quick Reference Guide

We manufacture a variety of dispersion blades and disperser equipment. Three key concepts surrounding dispersion are important to understand before ordering your dispersion blade or disperser. How Dispersion Works Dispersion is a high-speed, high-shear process requiring more horsepower to successfully achieve than simple agitation for smaller batch sizes. As the dispersion blade turns, particles contact the blades and are broken apart. In the intense turbulence surrounding the blade, particles collide at high speeds and are further broken apart. Beyond the zone… Read More

How Dispersion Works

High shear dispersion works when particles contact a rotating dispersion blade and are broken apart. The process requires equipment with high RPM and HP in order for the dispersion blade to reach tip speeds of 2,500 to 5,000 feet per minute. The optimum action of a disperser is a combination of rotary and radial flow. A particle starting at the outer edge of the container should travel to the center of the vortex in less than 360 degrees. Mixing and… Read More

How to Choose Your Dispersion Blade Style

How to Choose Your Dispersion Blade Style All blade designs generate similar shearing energy, which is the hydraulic tearing apart of particles. C design blades shear slightly less and generate less heat than the others due to the lower number of teeth per blade. A. – Performance match for the Cowles blade – Our most popular dispersion blade – Used in manufacturing paint, clay slurries, paper, coatings, ink and more – Rugged and efficient design – Economical to use B….

How to Get the Most From Your Dispersion

1. Define Your Product Characteristics – Viscosity/Heat-sensitive? Thixotropic? 2. Choose Blade Design – Design A, B, C, or D by max recommended viscosity or E for cutting/shredding 3. Choose Blade Diameter – Approximately 1/3 the diameter of the vessel 4. Blade Positioning – Locate one full blade diameter off tank bottom – min depth above blade not less than below 5. Mounting Accessories – Determine if hubs adapters or shafts are needed to mount blade to equipment 6. Hole Pattern… Read More

Am I Mixing or Dispersing? What’s the Difference?

INDCO customer service representatives and engineers provide assistance with mixing equipment selection daily.  A common discussion with customers is the determination of whether a given application calls for a mixer or a disperser.   Mixing and dispersion processes both entail rotating equipment within a vessel to process liquid-based products. In the following paragraphs we will provide definitions, discussion of flow vs. shear, mixing and dispersion equipment differences and examples of each application type. “Mixing” is the creation of a homogeneous material… Read More

How to Assemble Dispersion Blades

INDCO presents a video guide to dispersion blade assembly. We focus on four types of assemblies in the demonstration. The TS-Series shaft for lab stirrers or drills, DS-series shafts for any 1/2″ chuck, HS-series adapters and finally bolt-on and weld-on hubs. We have 5 styles of dispersion blades to fit your mixing needs. The Design A blade, our most popular, is widely used as a standard in dispersions including paints, dye pigments and many more applications.  It consists of alternating… Read More

Dispersion Blade and Propeller Together?

At INDCO we talk daily with customers who use our equipment to achieve their mixing process needs.  While most are using what we would describe as conventional equipment setups and procedures we do encounter those that are less so.  One example that we are sometimes asked about is the use of a dispersion blade and a marine style or other axial flow impeller in combination on the same shaft.    Our response is that we generally do not recommend it for… Read More
